Abstract
L'invention concerne un filtre en nid d'abeilles ayant une valeur limite de régénération élevée, constitué par un corps cuit en nid d'abeilles colonnaire ayant une multiplicité d'alvéoles alignées parallèlement dans la direction longitudinale, et séparées les unes des autres par une paroi alvéolaire, l'une ou l'autre partie d'extrémité de chaque alvéole étant scellée. Le filtre en nid d'abeilles permet à un gaz d'entrer par une de ses extrémités et de sortir par l'autre. Il est caractérisé en ce que l'épaisseur de la paroi alvéolaire est dans la plage de 0,20 à 0,28 mm, et en ce que, dans le filtre en nid d'abeilles, aucune couche catalytique n'est fournie dans une région représentant 10 % de la longueur totale du filtre en nid d'abeilles côté sortie des gaz, et une couche catalytique est fournie dans une région représentant de 25 à 90 % de la longueur totale du filtre en nid d'abeilles dans une région représentant 90 % de la longueur totale du filtre en nid d'abeilles côté entrée des gaz. La conductivité thermique de la région dépourvue de couche catalytique du filtre en nid d'abeilles est supérieure à celle de la région pourvue d'une couche catalytique.
